Was 'Lizard Man' and ex partner death bikie hit?

POLICE are reportedly considering whether the death of a Gold Coast bikie associate known as the Lizard Man, and his former partner, may be a double murder.

Shelsea Schilling and her Bronson Ellery, a former Bandidos enforcer, were found dead at Mr Ellery's Southport unit on Friday.

While police have refused to formally comment on the case as investigations continue, police sources have told the Gold Coast Bulletin the deaths were now both being treated as suspicious rather than a murder-suicide, which was initially suspected.

Ms Schilling's mother, Bonnie Markwell Mobbs, reported her daughter missing on Friday after being unable to make contact with her since last Wednesday.

In several posts on Facebook, the Gold Coast woman has blamed Mr Ellery for her daughter's death.
